I did look into the White Clouds before I bought them. From what I understand (and at this point my knowledge is limited), since they have disappeared in the wild, all of the captive bred ones are being adapted to tolerate warmer water for tropical aquariums. The guys at the local store where I buy my fish (very knowledgeable and very helpful) assured me they would do just fine in warmer temps. (fingers crossed...but so far they seem to be healthy)
I looked into live plants, but to be honest this tank sat empty for about three years because I just didn't have the time to take care of it. I have the time now, but I really didn't want to deal with live plants. The silk ones look so nice in the tank, I'm not dissapointed a bit.
Thanks for the nice comments everyone!
